Operations and support expenses increased in the second quarter and for the first six months of 2026. The increase in the second quarter was primarily due to an asset abandonment charge associated with the reprioritization of our spectrum strategy, higher advertising expense, incremental customer co…
The increase for the first six months was primarily due to higher wireless sales volumes, which drove higher equipment, selling and bad debt expenses. The increase was also due to higher network costs that included vendor credits in the prior year, and
incremental customer costs related to our acquired mass markets fiber business, which were partially offset by cost reductions from transformation initiatives, higher restructuring charges in the prior year and lower content licensing fees.

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
